IMPROVEMENT lN MACHINES FOR UPSETTING RODS.

Specification forming part of Letters Patent No. 127,146, dated May 28,1872; antedated May 11,1872.

I, GEORGE G. Bunenss, of Bawsonville, in the county of Lorain and Stateof Ohio, have invented certain Improvements in Machines for UpsettingMetal Bars or Rods, of which the following is a specification:

The nature of my improvement relates to the construction of a machineadapted to upsetting large or small bars or rods of metal in an easy andexpeditious manner, as hereinafter more fully set forth, in which-Figure 1 is a side elevation view of the machine ready for use, and inthe detached plan views, like letters refer to like parts, as on themachine, Fig. 1. Fig. 2 is a plan View.

Parts A and B constitute the bed-plates. PlateAis rigidly secured to andon any suitable bench, O, and at one end of the same is an oblong slot,D, ordinarily about three inches wide and six long, and extendslengthwise through and under the plate, in shape and size to correspondwith the tongue E on 'plate B, the tongue E extending centrally from thebottom of the plate B, and passing through the open slot D, and into andunder the plate A to the other end of the same, on which is arrangedjournalbearings F F, in which the lever-journal G turns, and connectswith the under side of the end of the tongue E by means of gear-teeth onthe lever-journal G and on the under side of the end of the tongue E, bywhich the plates A and B may be drawn together or extended apart, as maybe desired. On the tops of the plates A and B, and about four inchesfrom either outer end, and about five inches from each other on eachplate, are arranged pins H X, which may be cast upon and form a part ofthe same; the said pins are usually made eight square to correspond withthe holes in the square or round eccentric blocks I I, which may be usedon pins X X or h h and in connection with the blocks I I; and on theopposite side of the plates A andB are arranged cam-levers J K, withround holes large enough to permit the said levers to fit on and aroundthe pins on either side of the machine to correspond with the blocks II. Thus, when a bar or rod requires to be upset the blocks I I areadjusted to the proper width as between them and the cam-levers J K, sothat when the bar or rod is placed in a heated condition betweencam-levers J K and blocks I I it may be firmly clamped and upset bymeans of the journal-lever G drawing the plates A and B together. L is acord, one end of which is made fast to cam-lever J the other end is thenpassed through the hole M, and then down through or around thefoot-lever N and back through the hole M, and is then made fast to thecam-lever K. Thus, as the lever N is pressed with the foot the cord ismade to act independently on the cam-levers J K to clamp the 1 baragainst the blocks I I. O is a steel strip made fast to the cam K insuch manner as to permit the end of the lever J to pass between it andthe lever K for the purpose of operating both levers J and K with orwithout the cord L and by one movement of the hand.

Goncentrically between the plates A B is an aperture formed by the slotD, and over the tongue E, within said aperture, may be arranged a centerblock, Q, with plane concave sides, and may be used either side up, andmay also be constructed and used with the sides in any other formdesired.

The object of my improvement is to provide an upsetting-machine that maybe readily adjusted to any size bar or rod within its largest capacitywith equal facility, and so arranged as to be worked upon either side ofthe machine desired.

What I claim is- 1. The combination of the adjustable round or squareblocks I I, which are provided with holes to correspond in shape andsize with the pins H X and K X, which pins hold the blocks I I rigidlyas adjusted, in combination with the plates-A B and center plate Q, asand for the purpose set forth.

2. The arrangement and combination of the cord L with the cam-levers J Kand foot-lever N, substantially in the manner and for the purpose setforth.

GEORGE G. BURGESS.
